Win 7 Updates

I have a Win 7 laptop that I have been using since July of 2009. It has gradually slowed down over the years and I recently deleted a lot of software (it is no longer my primary laptop). I know that Win7 is no longer supported,(new updates, etc) but if I wipe the laptop and re-install Win 7, will I be able to get all existing updates? Same question for Office 2003.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
